What is the average distance from the Sun to the asteroid belt in kilometers?
How far away is the asteroid belt? Because the asteroid belt is between the Mars and Jupiter orbits, it is around 2.2 to 3.2 Astronomical Units (AU) from the Sun – which is approximately 329,115,316 to 478,713,186 km. The average distance between objects is a massive 600,000 miles.
How many kilometers does the asteroid belt span?
Distance from Earth: From this vantage point, the distance between Earth and the Asteroid Belt ranges from 3.2 and 4.2 AU – 478.7 to 628.3 million km (297.45 to 390.4 million mi).
What asteroid belt is closest to the Sun?
Kuiper belt
The Kuiper belt (/ˈkaɪpər, ˈkʊɪ-/) is a circumstellar disc in the outer Solar System, extending from the orbit of Neptune at 30 astronomical units (AU) to approximately 50 AU from the Sun. It is similar to the asteroid belt, but is far larger – 20 times as wide and 20–200 times as massive.
What is the average distance between asteroids in the asteroid belt?
about five million kilometers
Even if there were 100,000 sizable asteroids (more than a few kilometers in size) in the asteroid belt–and the real number is quite likely about ten times less–the average separation between them would be about five million kilometers. That is more than ten times the distance between the earth and the moon.
Do asteroids hit the Sun?
No asteroids have ever been observed to hit the Sun, but that doesn’t mean that they don’t! Asteroids are normally content to stay in the asteroid belt between Mars and Jupiter, but occasionally something nudges them out of their original orbits, and they come careening into the inner solar system.
What is the biggest asteroid?
1 Ceres
1 Ceres – The largest and first discovered asteroid, by G. Piazzi on January 1, 1801. Ceres comprises over one-third the 2.3 x 1021 kg estimated total mass of all the asteroids. Studied from orbit by the Dawn mission in 2015-2016.
